Zoltán Köntös, a Budapest-based engineer at IOI Investment Zrt., has just opened a new chapter in the story of human survival beyond Earth. His team’s theoretical analysis, published in the journal *Inventions* as “Photocatalytic CO₂ Conversion via the RK-X Process,” lays out a practical blueprint for turning Martian air and ice into two things astronauts cannot do without: oxygen and energy.
The RK-X process is not science fiction. It is a scaled-up version of a technology already proven in Hungarian industrial plants, where fulvic acid drives a photocatalytic cycle that splits carbon dioxide and water into formic acid and oxygen. Under Martian conditions, a single module sized to process just 10 tonnes of CO₂ per Earth year would yield enough oxygen to support six people for two years—with a safety margin to spare. “We’re not promising miracles,” Köntös says. “We’re showing that with equipment we already know how to build, we can close the loop on life support without hauling every breath from Earth.”
The commercial stakes are immediate. Shipping oxygen to Mars costs between $1.82 million and $3.64 million per crew member per year. Storing equivalent energy in lithium-ion batteries would run $30 million to $61 million for a one-time use. Formic acid, by contrast, stores 15.25 megawatt-hours as a stable liquid at room temperature, with a round-trip efficiency of 68.64%. A modest 55-square-meter solar array can power the reactor during daylight, while a compact nuclear unit offers continuous operation during dust storms—and even provides heat for free.
Three gaps remain before boots can hit Martian regolith. First, the catalyst must prove itself at CO₂ pressures below 10 millibars and 15 °C. Second, engineers need reliable ways to extract both water ice and dry ice at scale. Third, the entire closed-loop system must run reliably in a single integrated demonstration.
What makes this work stand apart is its grounding in terrestrial practice. The same fulvic acid chemistry already turns waste biomass into valuable chemicals on Earth. “We’re not inventing new science,” Köntös notes. “We’re adapting a proven industrial process to a new address.” If the lab tests succeed, the RK-X module could become the first multi-purpose chemical plant on another world—supplying air, storing energy, and managing water without cryogenic tanks or endless supply missions.
For energy investors watching Earth’s own transition to renewables, the implications are hard to ignore. A technology that stores solar power as a stable liquid fuel in ambient conditions is exactly what grid operators seek. Scaling the same chemistry here could ease the pressure on lithium supplies and cut the cost of long-duration storage. Mars may be the proving ground, but the know-how could land back home faster than any rocket.
